If the vertices of a triangle are and then the equation of a bisector of is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
A1,7, B-5,-1, C7,4 Then the bisector of angle B meets side AC at D then ADDC=BABC By using distance formula, BA2=36+64=100⇒BA=10 BC2=7--52+4--12=144+25=169 ⇒BC=13 So ADDC=1013 Hence D8323,13123 Then the equation of a bisector of angle ∠ABC is…
